Abstract (en)
An ice detector (100) includes a pair of electrodes (112;113-116) connected by a pair of leads (116a;117-120) to a control unit (121) which measures the admittance between leads to thereby sense and detect the presence of ice and other contaminants formed on top thereof utilizing a detection circuit (130). The electrodes are integrated into patch (334) which can be placed at different locations on an aircraft. <IMAGE>
